title: [Circular permutation of DNA molecules of Streptomyces griseus Kr actinophage Pg2].
abstract: DNA molecules of phage Pg2 have terminal repetitions and are partially circularly permuted. This was established by denaturation self-reannealing experiments and analysis of the distribution of denaturation loops in partially denatured Pg2 DNA molecules. The genome size is 40.8 kb, terminal repetitions are of about 2.2%, the degree of permutation is 35%. On the basis of the data on DNA melting temperature the content of GC pairs was found equal to 65%.
